Ya, the potential for not being interested in the spotlight characters was a concern for us as well. But we included the ability to spend time with the characters even on their non-romance routes, and doing so can provide both information, an enjoyable experience, and in Monica's case
And as I also said before here, I think some of you that didn't find at least Zarah's model appealing before, may have a change of heart or some other body part.
So we are going to likely include a way back into her good graces if you are so inclined and show some interest.
Though you can opt out when on the non-romance Monica and Zarah paths, I highly recommend you don't. There is both plot and backstory you can find on both paths... aside from some pretty epic bedroom antics.
